Description

Technical Field

[0001] The utility model belongs to the field of water conservancy gratings, and particularly relates to a water conservancy grating with a quick-disassembly and quick-assembly structure. Background Technique

[0002] A water conservancy grating is a device commonly found in water conservancy and sewage treatment facilities. It is mainly used to filter suspended solids and impurities in water bodies to protect subsequent water treatment equipment from being blocked or damaged. When water is transported through a water channel in water conservancy, there will be floating garbage in the water flow. In order to isolate the floating garbage and suspended solids, a grating is placed in the water flow, thus playing an interception role to prevent them from entering the subsequent water treatment system. After long-term interception, one side of the grating will be blocked by the intercepted objects. By regularly cleaning the intercepted impurities, the water conservancy grating helps to keep the water body clean, improve the transparency of the water body and the ecological balance. When the grating needs to be cleaned, inspected or replaced, if the process is complex or time-consuming, it will greatly reduce the maintenance efficiency, which may cause the system to be unable to operate normally for a long time, affecting the continuity and reliability of water treatment. At the same time, when the grating is temporarily removed and the new grating has not been installed or there is a time difference during the installation process, a window period for intercepting suspended solids and impurities in the water will be formed during this period, increasing the risk of water body pollution.

[0003] Therefore, a new structure is needed to solve the above problems. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a water conservancy grille with a quick-release and quick-assembly structure, including: a U-shaped frame 100 and a grille assembly 200. A U-shaped groove 110 is formed inside the U-shaped frame 100, and the grille assembly 200 is installed inside the U-shaped groove 110. It is characterized in that a chute 120 is opened on the front side of the inner wall of the U-shaped groove 110;

[0026] The grille assembly 200 includes a first grille plate 210 and a second grille plate 260. A slide bar 220 is connected to the left side surface of the first grille plate 210. A trapezoidal groove one 230 is formed by downward depression on the right side of the upper surface of the first grille plate 210. The right end of the first grille plate 210 is connected to the second grille plate 260. Multiple groups of grille holes 240 are formed through the front and rear surfaces of the first grille plate 210 and the second grille plate 260. A cutting plate 250 is provided at the bottom of the first grille plate 210. A trapezoidal groove two 270 symmetrical to the trapezoidal groove one 230 is formed by downward depression on the left side of the upper surface of the second grille plate 260. A connecting rod 300 is provided inside the trapezoidal groove one 230 and the trapezoidal groove two 270;

[0027] A railing 130 is fixed below the rear side inside the U-shaped groove 110, and two groups of symmetrical inclined rods 400 are connected behind the railing 130.

[0028] Please refer to Figure 3 and Figure 5 , the cross-section of the connecting rod 300 is in the shape of two trapezoids symmetrically spliced. The left and right sides of the connecting rod 300 respectively extend into the trapezoidal groove one 230 and the trapezoidal groove two 270. A pull ring is provided at the top of the connecting rod 300. The connecting rod 300 formed by splicing two trapezoidal structures can avoid the left and right movement between the first grille plate 210 and the second grille plate 260 and cause separation when entering the trapezoidal groove one 230 and the trapezoidal groove two 270.

[0029] Please refer to Figures 1 to 4 , grooves are formed by inward depression on the upper sides of the front surfaces of the first grille plate 210 and the second grille plate 260. Cutting plates 250 are connected to the bottoms of the first grille plate 210 and the second grille plate 260. The top front side of the cutting plate 250 inclines from the top to the bottom rear side to form an inclined surface. The setting of the grooves facilitates lifting the first grille plate 210 or the second grille plate 260.

[0030] Please refer toFigure 1 and Figure 2 Inside the front side of the U-shaped groove 110, two groups of grille assemblies 200 are symmetrically installed. The two groups of grille assemblies 200 are symmetrically attached to each other. The grille assembly 200 located at the rear side is attached to the front surface of the railing 130. The setting of the railing 130 can provide lateral support for the lower side of the grille assembly 200.

[0031] Please refer to Figures 1 to 4 On the left and right surfaces of the U-shaped groove 110, two groups of sliding grooves 120 are recessed inward. Four groups of sliding bars 220 are assembled inside the four groups of sliding grooves 120. The four groups of sliding bars 220 are respectively installed on the left side surfaces of the two groups of grille plates one 210 and the right side surfaces of the two groups of grille plates two 260. The cooperation between the sliding bars 220 and the sliding grooves 120 can fix the grille plates one 210 and the grille plates two 260 inside the U-shaped groove 110 and prevent them from tipping backward.

[0032] Please refer to Figure 1 and Figure 4 On the upper sides of the front and rear surfaces of the U-shaped frame 100, two groups of fixing holes are drilled. The four groups of fixing holes respectively extend into the two groups of grille plates one 210 and the two groups of grille plates two 260. Insertion rods are assembled inside the fixing holes. The opening of the fixing holes can limit the up and down movement of the grille plates one 210 and the grille plates two 260 inside the U-shaped groove 110 by assembling the insertion rods inside them.

[0033] Please refer to Figure 2 On the left and right sides of the bottom of the U-shaped groove 110, two groups of fixing holes are formed by penetrating downward. Fixing piles are provided in the two groups of fixing holes.

[0034] Example 1: During actual installation, first place the side of the U-shaped frame 100 with the connecting rod 300 and the diagonal rod 400 installed on its surface facing away from the water flow direction. By inserting the fixing pile into the interior below the installation position to be installed, the fixation of the U-shaped frame 100 can be completed.

[0035] Then, start to install the first group of grille assemblies 200 located inside the front side of the U-shaped groove 110. Through the cooperation between the sliding bars 220 connected to the grille plates one 210 and the grille assemblies two 260 and the corresponding sliding grooves 120, the grille plates one 210 can be placed downward from above the U-shaped frame 100 inside the left side of the U-shaped groove 110, and at the same time, the grille plates two 260 can be placed downward from above the U-shaped frame 100 inside the right side of the U-shaped groove 110. When the grille plates one 210 and the grille plates two 260 enter the U-shaped groove 110, they respectively move through the sliding bars 220 in the corresponding sliding grooves 120. At this time, the trapezoidal grooves one 230 and the trapezoidal grooves two 270 at the tops of the grille plates one 210 and the grille plates two 260 are symmetric with each other. By inserting the sliding bars 220 into the trapezoidal grooves one 230 and the trapezoidal grooves two 270, the rapid installation of the grille assemblies 200 located inside the front side of the U-shaped groove 110 can be completed.

[0036] At this time, the second group of grille components 200 is installed at the rear part inside the U-shaped groove 110. By flipping a new group of grille plates one 210 and grille plates two 260 by half a turn respectively, and then operating according to the above steps, it is possible to install the new group of grille plates two 260 behind the grille plates one 210 that have been installed, and at the same time install the new group of grille plates one 210 behind the grille plates two 260 that have been installed, thereby completing the symmetrical installation of the two groups of grille components 200, and the surfaces of the four groups of cutting plates 250 are mutually attached. When both the two groups of grille plates one 210 and grille plates two 260 contact the bottom of the U-shaped groove 110 through the cutting plates 250, by inserting the insertion rod into the fixing hole on the surface of the U-shaped frame 100, the grille components 200 can be fixed inside the U-shaped groove 110, and thus the rapid installation of the two groups of grille components 200 is completed. Water flows through the internal grille holes 240 of the two groups of grille plates one 210 and the two groups of grille plates two 260, and the grille plates one 210 and grille plates two 260 located on the front side can intercept the garbage and suspended substances in the water flow.

[0037] Embodiment 2: When it is necessary to clean, inspect or maintain the grille components 200, the above steps can be operated in reverse. It is possible to quickly remove any one group of grille components 200 from the inside of the U-shaped groove 110, and at the same time, the non-dismantled group of grille components 200 can intercept the garbage and suspended substances in the water flow, avoiding the influence of the blank period formed during the disassembly of the grille components 200 on the interception of the water flow. At the same time, it is possible to only remove any one group of grille plates one 210 or grille plates two 260, reducing the working intensity.

[0038] And when reinstalling into the U-shaped groove 110 after removing any one group of grille components 200, the bottom cutting plate 250 of the reinstalled grille components 200 can move while attaching to the surface of the other group of grille components 200. Because an inclined surface is formed at the bottom of the cutting plate 250, when the cutting plate 250 moves downward while attaching to the surface of the corresponding grille plate one 210 or grille plate two 260, the impurities below the cutting plate 250 can be pushed away. If the bottom of the cutting plate 250 is a flat surface, it may cause the impurities to flow to its bottom, affecting the rapid reinstallation of the grille plate one 210 or grille plate two 260 to the bottom of the U-shaped groove 110.

[0039] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
